Living in space stations or travelling to the next star.

A complete theory of the basic laws of the universe (which will combine quantum theory with Einstein's theory of relativity).	
32 - 45	What major technological advance does Hawking believe will occur in the next 1000 years?

We will learn to improve human beings by redesigning human DNA.	
63 - 70	What currently limits the size of the human brain?

The birth canal - as the brain has to pass through it.	
65 - 71	How will human beings get over this limitation?

They will learn to grow babies outside the human body.	
70 - 76	Why does he say we can't be both quick-witted and intelligent?

The chemical messages used in mental activity are slow-moving so bigger brains will be slower brains.
